Abstract
The invention relates to an active laser material having a base material doped with active ions, giving said base material laser properties, the ion concentration being equal to or higher than 2%. The invention also relates to a microlaser produced with such a material, as well as a process for producing such a material. The microlaser incorporates an active medium (6) produced by epitaxial growth on a substrate (8), the latter then being removable, as well as microlaser cavity mirrors (2, 4). A pumping beam (10) makes it possible to optically pump the cavity.
